Chapter 5 The Web Configurator

2Delete all port-based VLANs with the CPU port as a member. The “CPU port” is the management port of the Switch.

3Filter all traffic to the CPU port.

4Disable all ports.

5Misconfigure the text configuration file.

6Forget the password and/or IP address.

7Prevent all services from accessing the Switch.

8Change a service port number but forget it.

Note: Be careful not to lock yourself and others out of the Switch. If you do lock yourself out, try using out-of-band management (via the management port) to configure the Switch.

5.6Resetting the Switch

If you lock yourself (and others) from the Switch or forget the administrator password, you will need to reload the factory-default configuration file or reset the Switch back to the factory defaults.

5.6.1 Reload the Configuration File

Uploading the factory-default configuration file replaces the current configuration file with the factory-default configuration file. This means that you will lose all previous configurations and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and flow control set to none. The password will also be reset to “1234” and the IP address to 192.168.1.1.

To upload the configuration file, do the following:

1Connect to the console port using a computer with terminal emulation software.

2Disconnect and reconnect the Switch’s power to begin a session. When you reconnect the Switch’s power, you will see the initial screen.

3When you see the message “Press any key to enter Debug Mode within 3 seconds ...” press any key to enter debug mode.

4Type atlc after the “Enter Debug Mode” message.
